Abstract
Isolated stomachs from mammals showed substantial active absorption of sodium (Am.J. Dig. Dis. 14:221-238, 1969) in contrast to isolated frog gastric mucosa. Could the difference have been due to a "micro-environment" in the latter preparation based on fine structure features that maintained high H-ion concentration at the site of active transport? To answer this, H-ion secretion was inhibited in frog gastric mucosa with 15 mM thiocyanate. Unidirectional fluxes of sodium were not materially affected. These results cast doubt on a possible depression of active sodium absorption by a high H-ion concentration in the "microenvironment" of the isolated amphibian mucosa.
